JSON Minifier

Remove every unnecessary space and line break from a JSON document. The input is parsed first, so you also find out if it is invalid, and the output is guaranteed to be valid JSON.

• Validates while it minifies
• Reports how many bytes were saved
• Runs in your browser; the data is not uploaded

Does minifying change the data?

No. Only whitespace outside strings is removed. Keys, values and their order stay the same.

Input: text. No account needed within the free limit; a token with tools.tool.run raises it.

curl -X POST https://openvibe.tools/api/v1/tools/jsonminify/run \
  -H 'Content-Type: application/json' \
  -d '{"input":{"text":"{\n  \"a\": 1\n}"}}'
